pumped gallium motor windings stay cool
higher magnetic fields mean more power. Running high currents through carbon tubes full of pumped gallium might create much higher power motors at a particular size that remain cool enough to function at higher currents | |
I am thinking of robot improvements, so better motors are better.
Higher magnetic fields mean more power. Running high currents through carbon tubes of tinier than usual wire diameter full of pumped gallium might create much higher power motors at a particular size that stay cool.

Beany baby! Where ya bean? |

As to the idea, is your point that the gallium-filled tubes are supposed to be more electrically conductive than regular copper wire? Or is it that the pumped gallium carries away heat better? |
|
| |
He's suggesting that carbon tubes full of gallium will do both. |

//He's suggesting that carbon tubes full of gallium will do both.// That can't be - I have but one bone to give. |
|
| |
Also, why carbon tubes rather than copper? |
|
| |
Will gallium flooded carbon nanotubes engineer better,
faster free flowing electron paths? I don't |

To avoid certain undesirable properties that arise when you make nano ones (link). |

Not in Monopoly it's not. |

So nobody likes a Baltic Avenue slumlord. Got it. |

This is rather interesting, but obviously you need
something magnetic and gallium unfortunately isn't. |
|
| |
[RayfordSteele], the Gallium is for the electric field (instead of Copper) so doesn't need to be magnetic.
I would be worried about the Gallium and carbon tubes not playing nice. Can (liquid) Gallium be piped through tiny capilliaries? |
|
| |
Seems that it doesn't "wet" graphite, so it might flow OK, although the thermal conductivity is a bit low (considering one of the reasons to use it is to provide heat transfer). |
|
| |
I think you'll do much better forming heat pipes from the carbon with an appropriate vaporizing liquid. |
|
| |
I thought of using mercury, but according to
Wolfram|Alpha its specific heat capacity and thermal
conductivity are much lower than gallium's. I can't tell if
it's using solid or liquid gallium without comparing the
number it gives to another source, which is too much
work, though, so take that with a grain of salt. I also
asked about Field's metal, but Wolfram|Alpha doesn't
know what that is. |
